Question

in each of the following. find the centre and the radius of the circle (x+6)²+(y-4)²=36​

Answer 1

Answer:

Center  (-6, 4)  and  radius = 6

Explanation:

$(x + 6)^{2} + (y - 4)^{2} = 36$

Compare with the general equation of circle

$(x - h)^{2} + (y - k)^{2} = r^{2}$

we get  h = -6,  k = 4, r = 6

center  (-6, 4) and radius  = 6
